LEAsInG' COMB.

Application filed April 20, 1825. Serial No. 24,343,

The object of this invention is the provi sion of a simple, cheap and etlicient leasing comb for use in connection with a ball warper or other machine.

In th accompanying drawings, Figure 1 is a fragmental side elevation of a leasing comb embodying the features oi my invention.

Fig. 2 is a fra mental longitudinal sectional View of the comb.

Fig. 3 is a transverse sectional view of the comb showing the comb in its upper position.

4 is a similar view showing the comb in its lower position.

Fig. 5 is a diagrammatic view.

Figs; 6 and 7 are fragmental perspective views corresponding to Figs. 3 and 4-, respectively.

A leasing comb embodying the features of this invention may be employed in connection with warpers and other textile machines of various forms. In the diagram constituting Fig. 5, A represents the yarn mass being formed, and B are guides to which the threads extend from the creel and from which the threads pass through the leasing comb G and thence to the yarn mass A. V

The comb C is formed of splits or teeth 1, the lower portions of which are rigidly secured together and fixed to a structure constituting a back 2. The combis mounted in guides 3 for vertical movement. l/Vhile any preferred means may be employed to raise and lower the comb C, I have herein indicated means including a cam at mounted for pivotal movement on an axis 5. The cam 4- comprises a low portion or notch 6, a high portion or notch 7 and an intermediate notch 8, the back 2 being provided with a roller 9 arranged to rest in any of said notches. It will thus be seen that the comb C may occupy three different positions.

As shown in the drawings, the comb is open at the top for the reception of threads.

Alternate spaces in the comb are open from v the top to the upper edge of the back 2. Downward movement of the threads in the other spaces is limited by means of rivets 10 which extend between pairs of splits 1. Upward movement of threads in the last mentioned spaces is limited by lugs 11 which are struck laterally from one split of each pair and extend into an opening 12 in the other split of each pair. The upper surface .ofeach lug 11 is downwardly inclined'so as to permit a thread to slip down past it.

The lower edge of the lug is approximately horizontal and, as stated, extends into the opening -12 and thus bridges the space be tween the splits and thereby limits upward movement of a thread which has passed below the lug. 'VVhen the comb is in its middle position all the threads extend between the horizontal planes of the rivets 10 and lugs 11. as shown in Fig. 5.

The comb C being in its middle position,

the threads extending from the creel may be laid in the comb and attached to the yarn beam or other receiving yarn container. When it is deslred to form a lease in the threads the operative turns the cam i to the comb in its upper position, as shown in Fig. 3. The rivets 10 thereby .raise the threads which were previously depressed by the lugs 11 so as to elevate said threads above the others, as indicated in Fig. 3. In

to the shed thus formed a lease rod E is in serted. The lease rods are then replaced with the usual tapes, thus completing the leasing-operation. The comb is then restored to its normal middle position as shown in Fig. 5.

It will beis'een that the leasing comb herein disclosed is very simple in construction, cheap to manufacture, and efficient in operation,

I claim as my invention: 7

1. An open-top leasing comb having, in combination, sheet metal splits and a back, the splits being secured to the back, the thread-receiving spaces between the teeth being open at the top, rivets securing said splits together in pairs at points above the back, said rivets serving to limit downward movement of the threads in alternate spaces, the other spaces being unobstructed to permit the threads in said last-mentioned spaces to descend below the plane of said rivets, one split of each of said pairs having a ri gid lug struck iaterally therefrom, which lu extends partway into an opening formed in the other split of the pair, the upper side oi": said lug being downwardly inclined to slip down past it, the lower end 01": said lug serving to bridge the space between said pair of splits and prevent the thread from moving up past the lug.

2. A. leasing comb having, in combination, sheet metal splits and a back, the splits being secured to the back, the thread-receiving spaces between the splits being open at the top, and means securing said splits together in pairs at points above the back, said means serving to limitdownward movement of the threads in alternate spaces, the other spaces being unobstructed to permit the threads in said last-mentioned spaces to descend below the plane of said limiting means, one split of each of said pairs having a rigid lug struck therefrom, which lug extends partway into an opening formed in the other split of the pair, the upper side of said lug being downwardly inclined to slip down past it, the lower end or said lug serving; to bridge the space between said pair of splits and prevent the thread from moving up past the lug.

In testimony whereof, I have hereunto afiixed my signature.

BURT A. PETERSON,
